SPECIFICATION forming part of Letters Patent No. 581,262, dated April 27, 1897.

Application filed October 81,1896. Serial No. 610,670, (No model.)

To a ZZ wlwm it may concern-.-

Be it known that I, GUSTAV A. BRACHHAU- SEN, a resident of Rahway, Union county, State of New Jersey, have invented certain new and useful Improvements in Music- Boxes, of which the following is a speciiication.

My invention relates to music-boxes of that character wherein note-disks or rotary noteplates are employed to operate music-tongues or other sounding devices through interposed star-wheels or otherwise.

The said invention is an improvement upon the device covered in the patent to Braehhausen and Riessner, dated June 27, I803, No. 500,371; and it consists in the novel arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional View, with parts in elevation, of suflicient number of parts of a music-box to illustrate myinvention. Fig. 2 is an enlarged fragmentary sectional view of the same. Fig. 3 is a like view of a modified form of device embodying my invention. Fig. et is a view on the line 4 4: of Fig. 2. Fig. 5 is a like view on the line 5 5 of Fig. 3.

Upon the bed-plate A of the music-box is secured a pivot or pintle a, around which the note-disk B is adapted to rotate. This notedisk is preferably provided with note projections Z),which are intended to operate, through the star-wheels c or otherwise, the sounding device, which in the present instance consists of music-tongues (Z. (See Fig. a.) The notedisk is supported upon an adjustable sleeve 0, carried upon the pintle a, and is held in operative position thereon by the frictionrollers f, loosely carried upon the hinged rod 0, and which maybe maintained spaced apart by sleeves g or otherwise. The roll 0 is locked against movement when the parts are in the operative position by a latch y. Loosely carried upon the hinged red C is a spur-wheel h, which is adapted to engage the note-sheet near the outer edge thereof to rotate it.

In the construction illustrated in Fig. 1 the spur-wheel 7t has a pinion a: connected therewith, which pinion is engaged and driven by a geanwheel '1', operated from a suitable springmotor. (Not shown.)

In the construction shown in Figs. 3 and 5 the spurs on the spur-wheel 7L are adapted to engage in the recesses in'the female gear j when the parts are in the operable position, as indicated in Fig. 3. In this construction a pinion 71' is carried upon the female gear and rotates the note-disk through engagement with spurs on the spur-wheel, the pinion being driven by a gear Z, forming part of the train of gear of the spring-motor.

It will be observed that in both the constructions shown the spur-wheel is free to revolve upon the hinged rod until the spurs engage in the openings or engaging means 2 in the disk, when the spur-wheel is engaged by the driving means and prevented from further rotation.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a music-box, the combination of a note-disk having engaging means near the outer edge thereof, a hinged rod having rollers loosely mounted thereon, which rollers are adapted to bear upon the note-disk, a spurwheel loosely carried upon the hinged rod and adapted to positively engage the engaging means upon the note-disk, means for locking said rod against movement when the parts are in the operative position and means for positively engaging and rotating said spurwheel.

2. I11 a music-box, the combination of a note-disk having engaging means near the outer edge thereof, a hinged rod having rollers loosely mounted thereon, which rollers are adapted to bear upon the note-disk, a spurwheel loosely carried upon the hinged rod and adapted to engage the engaging means upon the note-disk, apinion carried by the spurwheel and a gear adapted to mesh with said pinion when the parts are in the operable position.
